Near the tank for the most part. However,,, some dragons just have their own funk so it could be just a personal thing.
I can't explain what a normal smell would be, it's just something you have to learn.
Now, not suggesting anything so don't bash me for this people.
In my opinion,, crickets make poo reek too. I switched to pellets/veggies, and small amounts of micro mealworms and the smell of the poo has gotten much better.
With that said,, the only way you will know if it's something going on is a fecal. If you find out it's coccida, you will remember that smell and know next time it comes around. I know when I go to shows, I can smell it at individual tables. It's just one of those things that sticks in your head.
Here is a pic of normal (parasite free) Poo. If yours is much more runny than I'd get it checked out. Certain foods can cause poo to be softer etc. so don't panic if it's not the same.
